FRITZ HOLZSCHEITER; OF ZURICH, SWITZER- LAND, ASSIGNORS TO MASCHINENFABRIK KIESSLING A.-G-., OF LEIIZIG, GERMANY MACHINE FOR SCORING WOODEN BOARDS Application filed October 13, 1927, Serial No. 226,002, and in Germany October The present iIlJZGIllJiOIl relates to a machine for scoring wooden boards on which veneer is to be applied. The main object of the invention is to provide a machine Which is t especially adapted to make the very minute scores in the surface of wooden boards which are to be veneered; the scores servin for retaining glue by which the veneer is astened on the board.
A further object of the invention is to provide a machine which will make scores parallel to each other at equal distances apart, and a still further object consists in providing an improved machine so constructed and ar- 13 ranged that two sets of parallel flutes are produced simultaneously thereby and which cross each other, say at a right angle. With'these and other objects in view the invention consists in the construction, combi- 26 nationand arrangement of devices hereinafter fully described and particularly pointed out in the claims.
In the accompanying drawings the machine is shown in a diagrammatical manner. Fig. 1 is a side elevation of the machine, Fig. 2 is a top view, 1; ig; 3 is a vertical section on line A-B of ig. 2, Fig. 4 illustrates the motor with part of the so driving gear,
F1Fig. 5 shows a section on line CD of Fig. 6 is aside elevation of a part of the chain carrying the scoring tools,
Fig.7 is a top view thereof,
Fig. 8 shows the mounting of the tool-chain on a driving gear,
Fig. 9 is a cross-section through a tool,
Fig. 10 shows a knife and Fig. 11 a scored board.
In thedrawings 1 denotes the frame'of the machine, 2 is a table adjustably mounted in .said frame 1. The table 2 restson two sup- 7 ports 3, 4 which are supportedby wedges 5, 6 movably frame'l of the machine. The table 2 may be adjusted in vertical direction by moving said wedges 5, 6, the table 2 bein secured by guide pieces 7, 8 against lateral isplacement. In 50 the two supports 3, 4 two rollers 10, 11 are re arranged in guide grooves of the.
14, was.
tatably mounted over which the endless band 9 runs. The band 9 is preferably of rubber,
and passes over supporting ledges arranged in a central opening of the table 2 and serves to forward the board to be worked beneath the tools as described hereinafter. lhe roller 10 is driven by a chain 13 (which is indicated indotted lines in Fig. 1) which runs over a chain wheel 12 fixed to the shaft of the roller 10 and over a chain wheel 14 fixed to an intermediate shaft 17 journalled in the frame 1 of the machine. The shaft l'? is driven from a wheel 16 by means ofa chain 15 (which is shown in dotted lines in Fig. 1), the wheel 16 being keyed on a shaft 17*. The shaft 17 is driven by a motor 18 by means of two spur wheels 20, and a speed reduction gear 21. The wedges 5, 6 are adjusted by screw threaded spindles 22, 23, rotatably mounted in the frame 1 and screwed into the wedges 5, 6. To rotate the spindles 22. 23 a suitable gearin 25 of known construction is provided (whic is indicated in dotted lines in Fig. 1) which is driven by a crank etc.
Above the table 2 and the horizontal por tion of. the band 9, two endless chains 26 are arranged extending across the table 2. The
chains 26 are positioned parallel to each other and run in opposite directions to each and at right angles to the direction in which the band 9 runs (Fig. 2). Each of the chains 26 runs over two chain wheels 28, 29 rotatably arranged in supports 30 rigidly fixed to the bed 1 and driven by means of two helical gears 33, 34, fixed on a shaft 35. The shaft which is journalled on top of the sup orts 30 is driven bya chain 36 from the shail; 17, the chain 36 running over twoidle rollers 38, 39 and over a chain gear 40 on shaft 35. The helical gears 33, 34 respectively drive the shafts 41, 41 of the sprocket wheels 28,29 by helical gears 42, 43 with which said shafts 41, 4E1 are provided. The wheels 28, 29 and therewith the chains 26 run in opposite directions to each other, and each is provided with two toothed flanges (Fig. 5).
Each chain 26 comprises an equal number (Fig. 5) of link plates which are arranged in spaced relation and are connected together by links 51 and bolts 52 other,
(Fig. 7). On each plate 50 four rollers '53 are rotatably mounted, the rollers 53 engaging grooves 54 (Fig. 8) in the supports 30. aid
ooves 54 run parallel with the upper lea of the band9 and the rollers 53 engage the ooves 54 with practically no backlash. (I; each plate a shoe 55 is slidably mounted '.on bolts 57. The front portion is slightly bent-ofi at 56 to facili- 7 tate the gliding ofsthe shoe on the wooden board B constituting the work (Fig; 8). A spring 58" coiled around on a bolt 57 abutting on plate 50 and shoe 55 tends to press the shoe 55 downwards and keeps the shoe in close contact with the surface of the board B to be scored. On each shoe a knife 58 is removably held by screw bolts. The working edge of the knife 58 is ser-' rated, the teeth 59 being close to each other, and the distance between two adjacent teeth is about 1 to 3 mm. The teeth 59 protrude slightly beyond the lower gliding face of the shoe 55. The knife 58 and the edge 56 run at an angle of 45 to the line of travel of the chain. In the. path of the knives 58 project rotating brushes 60 which brush off the chips taken off the board B by the teeth 59. The brushes 60 are driven from the shaft 35 by means of helical gears 61, 62, and sprocket wheels 63 and chains 64.
Balls 70 housed at the ends of the bolts 52 are adjustably mounted, run on the walls of the guide grooves 54 and prevent lateral plaly of the chains.
. o 'press'the board B on to the rubber band 9 four rollers 65 are provided. The rollers 65 are covered with a mantle of rubber'and are jour'nalled in blocks 67 movable against the action of springs 66 in vertical slotson the support 30.
The speed of the band 9 and therefore the speed of the board B carried by said band 9 beneath the rollers 65 and the tool chains 28, 29 is equal to the speed of said tool chains 28,29. The teeth 59 of the knives 58'cut shallow rooves C scores or flutes in the upper face 0 the board B. Said scores or scratches may run at 45 to the direction in which the board is moved by the band and the scores produced by the one tool chain 28 cross the scores produced by the other chain 29 at 90 (Fig. 11) as the two chains run in opposite directions. The length of the knives 58 and their distance apart is such that the scores produced by one knife are close to those produced by the preceding knife, the distance therebetween being equal to the pitch of the teeth 59.
The means to adjust the table to suit varying thicknesses of boards are well known as well as their operation and need not be described.
What we claim and wish to secure by U. S. Letters Patent is 1. In a machine of the class described, the
work so combination of means to feed the work in one direction tool carrying means arranged to move a tool across the work ina direction at an angle to that of the movement of the t at the movement of the tool across the work is diagonal to the movement of" the tool and also diagonal to the direction of movement or the work, said tool carrying means bein an endless chain comprisin plates flexib y connected together and em plate being provided with a 'shoe to move over the surface of the work and with a tool carried by said plate.
2. A machine as claimed in claim 1, in which the tool carrying means is an endless chain comprisin plates flexibly connected together and eac plate is rovided with a shoe to move over the sur ace of the work and with a tool carried. by said plate, said shoe being movable to some extent toward and from the plate and a spring being rovided which is active to move the shoe rom the plate to press the shoe and the tool carried thereby against the work.
3. A machine as claimed in claim 1, in whichthe .tool carrying means is an endless chain comprising plates flexibly connected together and each plate is provided with a shoe to move over the surface of the work and with a tool carried by said plate and provided with a serrated edgepresented to the work.
In witness whereof we aflix our signature.
